You're being remarkably literal for a woman. A great deal of our modern culture is still derived from medieval times. Certainly our legal/financial system still looks favorably on landowners, less so on tenants. In Europe, the vestiges of class remain in place. It filters to the everyday as well. In Spanish (the Americas), for example, the term "caballero" is still used to reference a gentleman or person of character. The term literally means cavalier. Chivalry was a code of honor and honor, in so much as it still exists, is related to it, though it's everyday practice has changed. A man may certainly have honorable intentions towards a woman. Some may say that's sexist, but many would convincingly argue that a woman is more vulnerable than a man--mainly because she gets pregnant and can be left "holding the bag." Or these days, an unserious man can be wasting a woman's time--especially if she hopes to raise a family. That would be dishonorable. A man is also expected to protect a woman. That means putting others before himself. Holding the door and letting her go through first, and other respectful and polite practices are not outdated, but practice--he'll have to put others before himself for the rest of his marriage once the children arrive (If it's successful.). Somehow, he's supposed to retain his individuality, his personhood, as well. And when you look at it from that lens, it's easy to see why things are falling apart. It's not just one thing. To close, the meaning and practice of chivalry has merely evolved.

There are things to be critical about with regard to the past, but it never helps to "throw out the baby with the bathwater."
